' Specification forming part of Letters Patent No. 133,597, datedDecember 3, 1872; antedated November 28,

following is a specification:

Nature and Objects of the Invention.

This stove differs radically from stoves before in use, and it may beadapted for burning any description of fuel. It is made with sloping orbeveled plates from the grate-bed to the outer edge. The sloping sidesdistribute the heat uniformly over the whole area of the stove and causethe heat to be radiated downward to the floor. They also afford superiorfacility for the introduction of pipes through which air is passed anddelivered within the oven in asuperheated state, rendering the bakingmore rapid and wholesome and less wasteful. Other pipes, also passingthrough the combustionchamber, serve as heaters and ventilators,delivering the heated air into the room. The stove is further providedwith a box or casing of tin or other sheet metal to b e placed over thetop, coverin g the cooking-vessels and communicating with thedischarge-fines, so as to completely carry off all effluvia fromcooking. This casing is furnished with doors, so that it may be tightlyclosed at all times, excepting when it is necessary to introduce,remove, inspect, or manipulate the articles which are cooked.

Description of tlwDmwiag.

Figure 1 is a plan or top view of my improved stove, partly in section.Fig. 2 is a vertical longitudinal section of the same in the planeindicated by the line a: m, Fig. 1. Fig. 5 is a transverse section onthe line y y, Fig. 1. The arrows indicate the directions in which therespective sections are taken.

A represents the oven. B B, Figs. 2 and 3, are pipes open at their lowerends in. the rear part of the stove, passing through thecombustion-chamber K, and communicating at the upper ends with theinterior of the oven for the purpose of supplying superheated airthereto. 0 0, Figs. 1 and 2, are air-pipes communicating with theatmosphere both above and below, and passing through thecombustion-chamber, so that the heat will cause an active current of airthrough the said pipes, the air bein g taken in near the floor in a coldstate and being discharged above in a heated state, for the purpose ofwarming and ventilation. D, Fig. 2, is an exhaust pipe or duct forcarrying off foul air from the oven and delivering it into the spacebetween the inner and outer I shells of the oven, which communicateswith the discharge-flue M and L L, the beveled or sloping sides, bywhich the upper part of the stove is extended horizontally in everydirection. E represents the central grate. F is a water-reservoir. G isthe ash-pan. H is the tin cover or casing, extending over the top of thestove and communicating with the discharge-flue either throughhorizontal pipes I I, delivering into the flue-space around the oven, orby means of an elbow applied to the collar J, as preferred.

Claims.

I claim as my invention- 1. The combined arrangement of the centralgrate E. sloping sides L, elevated oven A, the casing H occupying thespace in front of the oven, and the water-reservoir F occupying thespace beneath the inclined .back of the stove, all as herein shown anddescribed, for the purpose specified.

2. The combination and arrangement of the oven A, air-pipes B, andexit-duct D with the combustion-chamber K and discharge-flue M, in themanner and for the purposes set forth.
